About Megapiranha

Just how "mega" was Megapiranha? Well, you may be disappointed to learn that this 10-million-year old prehistoric fish "only" weighed about 20 to 25 pounds, but you have to bear in mind that modern piranhas tip the scale at two or three pounds, max (and are only truly dangerous when they attack prey in large schools). Not only was Megapiranha at least ten times as big as modern piranhas, but it wielded its dangerous jaws with an additional order of magnitude of force, according to a recently published study by an international research team.

The largest variety of modern piranha, the black piranha, chows down on prey with a biting force of 70 to 75 pounds per square inch, or about 30 times its own body weight. By contrast, this new study shows that Megapiranha chomped with a force of up to 1,000 pounds per square inch, or about 50 times its own body weight.

The only logical conclusion is that Megapiranha was an all-purpose predator of the Miocene epoch, chowing down not only on fish (and any mammals or reptiles foolish enough to venture into its river habitat) but also large turtles, crustaceans, and other shelled creatures. However, there's one nagging problem with this conclusion: to date, the only fossils of Megapiranha consist of bits of jawbone and a row of teeth from a single individual, so a lot more remains to be discovered about this Miocene menace. In any event, you can bet that somewhere right now, in Hollywood, an eager young screenwriter is actively pitching Megapiranha: The Movie!
